Artificial intelligent skins hold the potential to revolutionize artificial intelligence, health monitoring, soft robotics, biomedicine, flexible, and wearable electronics. Present artificial skins can be characterized into electronic skins ( e-skins) that convert external stimuli into electrical signals and photonic skins ( p-skins) that convert deformations into intuitive optical feedback. Merging both electronic and photonic functions in a single skin is highly desirable, but challenging and remains yet unexplored. We report herein a brand-new type of artificial intelligent skin, an optoelectronic skin ( o-skin), which combines the advantages of both e-skins and p-skins in a single skin device based on one-dimensional photonic crystal-based hydrogels. Taking advantage of its anisotropic characteristics, the resulting o-skin can easily distinguish vector stimuli such as stress type and movement direction to meet the needs of multi-dimensional perception. Furthermore, the o-skin also demonstrates advanced functions such as full-color displays and intelligent response to the environment in the form of self-adaptive camouflage. This work represents a substantial advance in using the molecular engineering strategy to achieve artificial intelligent skins with multiple anisotropic responses that can be integrated on the skin of a soft body to endow superior functions, just like the natural organisms that inspire us.

用于多维传感的具有各向异性电学和光学响应的​​人工智能光电皮肤

人工智能皮肤具有彻底改变人工智能、健康监测、软机器人、生物医学、柔性和可穿戴电子产品的潜力。目前的人造皮肤可以分为将外部刺激转化为电信号的电子皮肤 (e-skins) 和将变形转化为直观光学反馈的光子皮肤 (p-skins)。将电子和光子功能合并到一个单一的皮肤中是非常可取的，但具有挑战性并且尚未探索。我们在此报告了一种全新的人工智能皮肤，即光电皮肤（o-skin），它结合了 e-skin 和 p-skin 的优点，在基于一维光子晶体水凝胶的单一皮肤设备中. 利用其各向异性的特性，由此产生的o-skin可以轻松区分压力类型、运动方向等矢量刺激，满足多维感知需求。此外，o-skin还展示了全彩显示、自适应伪装等对环境的智能响应等先进功能。这项工作代表了利用分子工程策略实现具有多种各向异性反应的人工智能皮肤的重大进展，这些皮肤可以集成在软体皮肤上以赋予卓越的功能，就像激发我们灵感的自然生物一样。o-skin还展示了先进的功能，例如全彩显示和以自适应伪装的形式对环境进行智能响应。这项工作代表了利用分子工程策略实现具有多种各向异性反应的人工智能皮肤的重大进展，这些皮肤可以集成在软体皮肤上以赋予卓越的功能，就像激发我们灵感的自然生物一样。o-skin还展示了先进的功能，例如全彩显示和以自适应伪装的形式对环境进行智能响应。这项工作代表了利用分子工程策略实现具有多种各向异性反应的人工智能皮肤的重大进展，这些皮肤可以集成在软体皮肤上以赋予卓越的功能，就像激发我们灵感的自然生物一样。
